' JOSEPH GRAssY, residing at 19 Place Tolozan,

Lyons, France, citizens of France, have invented new and useful Improvements in or Connected with Looms for Weaving, of which the following is a specification. I

The invention has for its object a mechanical embroidery or figuring apparatus combined with a loom for weaving in such manner as to be placed in operation or at rest at the desired times by the entirely automatic action of the jacquard, the loom reassuming its habitual work when the embroidery or figuring apparatus is at rest.

The accompanying drawings illustrate one method of applying to a loom for weaving an embroidery or figuring apparatus having three rows of shuttles.

Figure 1 is a sectional front view of the combined loom and embroidery or figuring apparatus. Fig. 2 is a cross-section of the same, showing the mechanism which operates the shuttles. Fig. 3 is a front view of part of the said mechanism. Fig. 4' is a cross-section showing the mechanism which operates the embroidery or figuring apparatus. Fig. 5 is a front view of part of the said mechanism, and Fig. 6 is a perspective view of some of the parts.

The'embroidery or figuring apparatus is constructed in the same manner as known figuring or embroidering battens working with one or several rows of shuttles; but in place of being fixed to the batten and-accompanying it in all its motions it is independent of the batten and does not follow it except when it is working, which when it is at rest enables the loom to work as an ordinary loom with throw of the shuttle at all the beats. For this purpose the embroidery or figuring apparatus Z2 is mounted .on a vertical frame 0 0, mounted on the shaft e, serving as pivot for the batten f. This frame can also move endwise by sliding on this shaft; When it is not required to work, the embroidery or figuring apparatus rests in the front of the loom t on the shaft.

in the position shown at Figs. 2 and 4. During this time the loom weaves the foundation in the ordinary manner. Before commencing to work it is brought by the jacquard to the .transverse position it should occupy according to the requirements of the design. This motion is controlled at the desired time (see Fig. 1) by a certain number of cords g g, attached to as many crank-levers h h, the vertical arms of which operate in one direction a connecting-rod k, attached to the frame 0 c, which is acted upon in the contrary direction by a spring 1'. The levers h operate the connecting-rod k by projections c' of different When the moment of commencing work has arrived, the jacquard pulls the cord m, attached to a crank-lever a, turning loosely on the shaft 8, Figs. 1, 4:, and 5, and turns this shaft inone direction only by means of the projection t onva lever engaging a'projection On the shaft 8 are keyed the levers an, operating on each side of the loom the extensible spring-connecting rods connected to the hooks .2, pivoted to the supports d of the batten. The hooks 2 when they are lowered by the pull of the cord m become hooked in the forward motion of the batten on the studs 0, fixed to the frame a, carrying the embroidery or figuring apparatus, which latter then becomes fixed to the batten, which takesit with it in its backward motion.

The embroidery or figuring apparatus 6 is carried by two rods 2 2, sliding vertically on the frame 0 and held upward by springs 1 1. Each. of these rods carries at its lower part a pulley 3,'guided in a slotted arm 4. fixed to the framing of the loom, the slot of which isinclined in such manner as to lower the embroidery or figuring apparatus 1n its rearward motion in order to cause the shuttles to enter the open part of the shed.

When the cord m is slackened by the jacquard, the hooks remain hooked, because the vertical arm of the lever a is hooked behind the shoulder of a horizontal lever a, and it is only after the return to the front of the embroidery or figuring apparatus that the projection p of a sleeve 1', fixed on the pickeroperating shaft 0, acts to raise the lever u and to liberate the hooks .2, which are again raised by the springs 5. hen the embroidery or figuring apparatus is required to work two or more shoots without interruption, a second cord m acts upon a second crank-lever n, which maintains the hooking in its turn, while the first lever or returns to the rear. "he lever n is also held by a lever a, raised by a second projection of the sleeve r diametrically opposite to the first. In this manner by the alternate pull of the cords an m the working of the embroidery or figuring apparatus may be rendered continuous or by the pull of a single cord it may be made to work once only at each pull, thus corresponding with all possible cases of embroidery or figuring.

While the embroidery or figuring appara tus is lowered in the warp, one or other of the rows of shuttles is operated in the following manner: On the picker-operating shaft 0, Figs. 1, 2, and 3, is keyed a drum q, carrying toothed segments 6 6, arranged in diametrically opposite pairs on as many separate rings as there are rows of shuttles to be moved. Each of these rings drives a pinion 7, which makes a half-rotation for each passage of a segment. Each pinion carries a connectingrod 8, which operates a three-armed lever 9, to which are attached on each side of its axis the ends of a cord 10, which passing under the pulleys l1 and over the pulleys 12, mounted on the right of the embroidery or figuring apparatus, passes around one of the pulleys 13, mounted on the left of the embroidery or figuring apparatus. (See Fig. 1.) The cord 10 is attached to one of the fingers a, governing the passage of the shuttles from right to left or the reverse. It results from these arrangements that at each half-rotation of the picker-operating shaft 0 the pinion 7 also makes a half-turn, and the connecting-rod 8 causes the lever 9 to pass from one extreme position to the other. The cord 10, operated by this lever, therefore causes the shuttles to pass from right to left or the reverse. The three rows of shuttles being operated in the same manner by as many similar mechanisms, it is only necessary to put these mechanisms in operation at the required time. For this purpose each pinion 7 is mounted on a lever 24:, mounted on a pivot at 25 and carrying on an arm a roll 26, which rests on a cam 27. Each of the cams 27 can be operated in one direction by the jacquard by means of a cord 28, fixed to its boss, and in the'other direction by a spring 29.

When one of the cords 28 is pulled, the cam 27 presents its raised part to the roll 26 and puts the pinion7 in gear withthe corresponding toothed ring of the drum q, the pinion 7 makes a semirotation, effecting, as has been described, the passage of the corresponding row of shuttles, and this as many times as the cord 28 is pulled by the jacquard. When the cord is at rest, the pulley 26 rests on the lower part of the cam, and the pinion 7 is not actuated.

In order to fix the pinion 7 in either of its two positions, each pinion is fixed to a disk 30, provided with two notches, in which a springpressed wheel-pawl 31 engages. By this arrangement the passage of the shuttles of any desired row in one direction or the other is obtained at the moment when the embroidery or figuring apparatus operates by the simple pull of one of the cords 28.

When the embroidery or figuring apparatus is not working, the shuttle of the groundweaving is shot, as usual, at all the beats of the batten; but it is important that it should not be capable of being shot when the embroidery or figuring apparatus is at work. The following arrangements give all security with this respect.

When the embroidery or figuring apparatus is not working, the action of the picking-sticks 14, Fig. 1, can take place when the shuttle has arrived in its corresponding box 15. For this purpose the picking-stick is operated by a segment 16, in which a pawl 17 engages, which is jointed to the picking-stick. The pawl 17 ordinarily is kept raised by the cranklever 18, so as not to be moved by the segment 16; but when the shuttle arrives in its box it pushes back the flexible lever 19, mounted on the shaft 19, which by means of the link 20, crank-lever 21, and connecting-rod 22 lowers the lever 18 and allows the pawl 17, by which the picking-stick is operated, to come into operation. This flexible lever 19 is sufficiently rigid to operate the parts when the hooks z are raised, but is merely bent sidewise by the shuttle when the hookse are low- 1 ered. It is this already-known arrangement which is utilized to prevent the shooting of the shuttle every time the embroidery or figuring apparatus works. For this purpose the rear end of the hooks 2 are simply connected by connections 23 to the levers 21 already operated by the shuttle. The result is that each time that the embroidery or figuring apparatus is working, the hooks 2 being lowered, the pawls 17 are raised by the levers 18 and that neither one nor the other of the picking-sticks can operate.

When the work of the embroidery or figuring apparatus is suspended and the hooks raised, the levers 21 are no longer influenced except by the shuttle, and the picking-stick capable of application with any convenient number of rows of shuttles and that a loom provided with a given number of rows of shuttles will be capable at will of Working according to requirements with a smaller number. The embroidery or figuring apparatus herein referred to as an example may also be replaced by an embroidery apparatus with a row of other forms of shuttles without in any Way modifying the mechanism described.

What we claim as our invention, and desire to secure by Letters Patent, is

1. In a loom for weaving, the combination of an embroidery or figuring apparatus inde: pendent of the batten, a frame by which the embroidery or figuring apparatus is carried, a

batten, a pivot on which the batten moves,

means for causing the frame to slide on the pivotof the batten, means withconnections to the jacquard for fixing the frame to the batten when it is required to work and for suspending the throwing of the ground-shuttle at such time, substantially as set forth.

2. In a loom for weaving combined with an embroidery or figuring apparatus, the combination of a batten, jacquard-cords, a series of crank-levers operated separately by said cords, there being unequal projections on'said levers, a connecting-rod k operated by said projections in one direction and by a spring in the contrary direction, a sliding frame operated by said connecting-rod, and embroidery or figuring apparatus carried by said frame, substantially as set forth;

' In witness whereof we have hereunto set our hands in presence of two witnesses.
